Parkinson’s disease is a severe brain disorder that may result in symptoms that are not noticeable in its early stages. However, the progressive disorder eventually damages the nervous system and various parts of the body controlled by the nerves. And while one could look for treatments to manage the disease, it isn’t easy to tell if someone has Parkinson’s disease because its symptoms may be similar to other health conditions. Here are eight signs that require the immediate attention of a healthcare expert. Loss of smell The loss of smell is usually associated with the onset of Parkinson’s disease. The individual might have trouble smelling foods like dill pickles, licorice, and bananas. The loss of smell (hyposmia) may result in reduced food satisfaction, which may degrade one’s appetite. It can lead to a reduced enjoyment of food and appetite. There are also other health conditions why one may lose their sense of smell, including a stuffy nose, cold, and flu. The individual may be able to smell foods once again when they get better. However, if the condition occurs suddenly, one should consult an expert for signs of Parkinson’s disease. Constipation The foods one eats may play a major role in overall health, especially in the gastrointestinal system.
